Edible leafstalks actors talk about (7)
I believe the answer is:
rhubarb
'talk about' is the definition.
'rhubarb' can be an answer for 'talk' (I have seen 'Meaningless talk ' mean 'rhubarb' so perhaps 'talk' could also mean 'rhubarb'). I'm not sure about the 'about' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for rhubarb that I've seen before include "Edible plant with fleshy reddish leaf-stalks (7)" , "Stage chatter" , "The pinkish stalks are edible, but the leaves are poisonous" , "Reddish leafstalks cooked and sweetened" , "perennial plant" .)
